Hello,
I am investigating Rs online recalibration possibilities (basing on lab7). The values of Rs_Ohm and RsOnLine_Ohm change constantly from about 0.003 up to 0.013 (gradually rising and falling) - is it normal? I suppose some oscillations are unavoidable, but at the motor with such low Rs it is a huge difference...
An off-line calibration gives me a value of about 0.009, so maybe it will be better to stick to it? What is the trade-off for running an online re-calibration all the time (doesn't the temperature rise due to additional current)?
On the other hand, the motor temperature will rise from 20 up to 80 degrees during runtime, so the Rs value may change accordingly.
Bonus question: can I do Rs Online Re-Calibration with the controller online, but the motor not spinning (ref speed 0)?
Thanks for any advice
